Randy, the Nology wires work WAY differently from Jacobs ignition sys. I know that, which puts MSD's unit up against Jacobs, on that front I've been told by many that Jacobs is superior. Currently I'm running 8.0mm wires from Korman. My quest./comp. is aimed at whether the FAST hot spark of Nology is better than the contoured spark of Jacobs "brain/coil sys."? I would think Jacobs. Thanks for the input though. Any input is worthy, MSD is better known than Jacobs so I figure more people run MSD's.
